Final answer:
The patient's symptoms are indicative of congestive heart failure.
Step-by-step explanation:
The patient's symptoms of weight loss, increased appetite, fatigue, heart palpitations, and pitting edema in the legs and face are indicative of congestive heart failure. Congestive heart failure occurs when the heart is unable to pump enough blood to meet the body's needs. This can lead to fluid retention in the body, resulting in edema and weight loss.
